There are no counter formations in the game anymore, not the obvious ones that were here in the past. This season I changed to a 3-1-4-1-1 with 3 DCs and surprisingly did very well with it, whereas people always said you desparately need wingers in your team as they are the best players.
I played 4-5-1 V as my main formation for years really and I would always agree on all of that, it's why I never really thought about changing it up.
I could see in the King of the Hill event, where you play the same opponents, probably with the same tactics and formation, multiple times, that I seem to do better against some teams than others on average. And against these where I didn't do to well, I tried other tactics and still didn't do well. So I don't really know, maybe formations are a thing, but if so, then not in a logic kind of way (my 3 DC formation does really well against 4-2-3-1 for example, which is strange as I don't have any wing backs) but more in a rock, paper, scissors kind of way.
